An emergency repair on southbound Interstate 5, as well as scheduled ramp closures on northbound I-5, will create delays for people who travel the interstate in Seattle Wednesday, Sept. 26, through early Monday, Oct. 1.

The first of the final projects to complete the reconstruction of State Route 520 in Seattle will resume in 2019 when crews break ground on the Montlake Project at the SR 520-Montlake Boulevard interchange. The Washington State Department of Transportation will announce a contractor for this work in the coming weeks. In 2020, crews will also begin building a new bus and carpool connection between SR 520 and South Lake Union via the Interstate 5 express lanes.

The opening of a new stretch of eastbound Interstate 90 marks the halfway point of a 15-mile improvement project to add lanes, build bridges, stabilize rock slopes, reduce avalanche closures and improve wildlife movement east of Snoqualmie Pass.
